U GUSTAV rfuous, F VIENNA AUSTRIA-HUNGARY. "LAMP-BURNER; FOR LIGHTIN AND HEATING PURPO ES.

110 all whom it my consent:

Beit known that I, GUSTAV FUoHs, manufacturer, a subject of the Em erorof Austria-Hung'ary, and a resident o Amerlingstrasse, in the city of Vienna, Province of Lower Austria,- and Empire of Austria-Hungary, have invented certain new and useful improvements in Lamp-Burners for Lightsuch lamps with burners which permit of a tral arms 9, the honzonta gases formed in the burner.

rapid current of air which keeps the wick cool and which is thoroughly mixed With the A further object of the, invention is to provide such burners in which the gases are developed only in the quantity required, so

that a Bunsen flame of high heating effect is formed, which may be used advantageously for heating urposes or with incandescent mantles for hghting oses. 1 a j The invention wi l e' hereinafter more full described and explained, with reference tot eaccompanying drawings, in which Figure 1 18 a vertical cross-section of .a lamp .and burner constructed according to, the invention, and Fig; 2 is a vertical crosssection of a modified form of the lamp and burner.

Referring more particularly to Fig. 1, the lamp-font 1 has inserted in its center two concentric tubes 2 and 3, secured to the bottom of the font 1 and carrying in the annular space between them the circular wick 4.

A further tube 5 in the font 1 surrounds the said tubes 2 and 3 and forms an annular space 6 around the outer tube 3. The central tube '-2 and the annular space 6 are open atthe bottom of the font 1. The annular space forming the wick-tube is connected at its lower end with the space of the font by means of the small radial tubes 7. On the u per end of the inner tub'e 2 is inserted a slibrt tube 8, made of a material non-conductor of heat. and supporting, by means of cen- .disk or button 10. The font 1 has secured to its up er ,part and extending above the tube 5 a cy drical. art

11, supporting on acorrespondin sho der '12 the tube 13,which is provide withthe Specification of- Letters Patent. -Applioatidn filed June 29, 1904. Serial No; 214,629,

edge 16 of said tube 13 is'bent inward toward ;the rim of the disk or button, and in its lower gallery 14 for the. chimney 15; The upper partsaid tube 13 is provided with air-holes 17; Theincandescent mantle 18 (indicated in dotted lines) is supported'in any welL known or usual manner. As shown by the several arrows, the air gains access to the flame through the central tube 2, theannular s ace. 6, andthe perforations 17 of tube 13, thereby cooling the wick-tube 2 3 from both sides, and is at the upper end of the burner thoroughly mixed with the gases developed at the upper end of the wick. The insulating-tube 8 prevents the wick-tube being heated toomuch.

The-other form of the lamp and burner shown in Fig. 2 has inserted 'in the lamp-font 1' a double wick-tube, the inner tube 2 of which extends down to the bottom of the font, while the outer tube'3' extends onlya certain distance down from the "top, so that the wick 4 hangs freely in the basin with its lower part. with, the-bottom of the font, a'hdthe' outer tube 3. is cast in one piece or otherwise-con nected with the top part 19 of thefont. On the top of the inner wick-tube 2 is inserted the short insulating-tube 8 in the same manner as in Fig. 1. The said inner wick-tube 2 has inserted and held by means of elastic arms 21 a central tube 20, extend' down to "the opening in the bottom of the ont, thus formin two central air-passages 22 and 23 on the 1nner side of the wick-tube.

'upper edge OffSfiid central tube 20 is inserted and seated with a shoulder '25 the tube 24, supportin on its. upper end the disk '10,

On the i The inner tube 2 is connected 80 I which in t e present case is perforated. 1 The top part 19 of the lamp-font 1 extends in a cone or bell shaped part 26, surrounding the wick-tube and having its upper edge 27 bent against andlying beneath the disk or button 10. Part 19 supports the tube 13 with gallery 14 and chimney 15. The tube 13' surrounds the cone 261 It is provided with air,- holes' 17, and its upper edge16 is bent in ward toward the dis 10 The top part 19 of the font is also provided with air-holes 28.

- The arrangement described creates two inner and two outer currents ofiair, as indicated by thearrows in Fig. 2 The current of air entering through the annular space 23 and t that passing on the inside of cone 26 serves to cool the wlck-tube in, itslupper part from bothsides and are below the edge 27 of the ing through the central space v22 passes lated by raising or through the perforations of the disk- 10 t0 the central art of the flame.

In both orms of'my lamp and burner the currents of air on the inside and outside of the wick-tube and the insulating-tube on the top of said wick-tube prevent the wick-tube becoming heated too much, and also the gases are developed only in the quantity required to form an eflicacious Bunsen flame. The development of gases is perfectly reguowering the wick by means of any suitable device, so that sooting of the lamp and deterioration of the air in the room caused by too-rapid development of gases may be easily prevented; On screwing thewick wholly down for extinguishingthe flame no more gases are developed. Having now described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

The combination with a font, of two centrally-arranged concentric tubes 2 and 3 secured to the font and forming between them an annular space for the wick, a tube 5 within the font and surrounding the first-mentioned two tubes and forming an annular space 6 around the outer one of said latter tubes, the said font being provided in its bottom with openings 6 to permit air to gain access to the space 6 at the lower end of the latter, small radial tubes 7 connecting the lower end of the wick-space with the interior of the font, a short tube of heatenonsconducting material carried by the tube 2, arms attached to the said short tube and a disk carried by said arms. 7

In testimony whereof I have signed my name in presence of two subscribing witnesses.
